Hi All,
I have a doubt regarding comparison of From-Tag,To-tag and
Via-branch for matching the transaction.
While comparing the tags and branch parameters, whether the comparison
should be case-sensitive or case-insensitive.
In section 7.3.1 of RFC3261:-
"When comparing header fields, field names are always case-
insensitive. Unless otherwise stated in the definition of a
particular header field, field values, parameter names, and parameter
values are case-insensitive. Tokens are always case-insensitive."
As per the grammar of From-tag and To-tag:-
tag-param = "tag" EQUAL token
and grammar of branch parameter of Via header is:-
via-branch = "branch" EQUAL token
In the definition of From,To and Via headers, there is no definition that
the values should be case-sensitive.
Does that mean that we should do case-insensitive comparison?
Please confirm on this.
